Radiation, flow of atomic and subatomic particles and of waves, such as those that characterize heat rays, light rays, and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation.
25 Ιαν 2023 · Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of radiation include the sun, microwave ovens in our kitchens and the radios we listen to in our cars.
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium. [1][2] This includes: electromagnetic radiation consisting of photons, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ)
8 Δεκ 2019 · Radiation Definition. Radiation is the emission and propagation of energy in the form of waves, rays or particles. There are three main types of radiation: Non-ionizing radiation: This is the release of energy from the lower-energy region of the electromagnetic spectrum.
Learn about radiation as energy or particles from a source that travel through space or other mediums. Find out about natural and artificial sources of radiation, background radiation levels, and ionising radiation effects.
Radiation is the term used for all phenomena characterised by the transport of energy, either by waves or sub-atomic particles. The highest energy waves can behave just like particles, and sub-atomic particles can behave just like waves. This is called the wave – particle duality.
25 Απρ 2024 · This chapter provides a summary of the fundamental principles and primary sources of ionizing radiation. It briefly revisits ionization processes in materials, delving into the essential laws governing spontaneous radioactivity and radioactive decay. The content...
